赤チームと青チームに均等にわけるコマンドを作りたいがなぜか均等にならない

command /randomteam:
    permission: sk.admin
    permission message: &cYou don't have permission.
    trigger:
        set {player} to 0
        delete {tempredteam::*}
        loop all players:
            if {team.%loop-player's uuid%} is not set:
                add 1 to {player}
                add "%loop-player%" to {tempredteam::*}
        wait 1 tick
        set {playerhalf} to {player} / 2
        loop {playerhalf} times:
            set {tempred} to random object out of {tempredteam::*}
            command "/team join red %{tempred}%"
            set {_uuid} to {tempred} parsed as player's uuid
            set {team.%{_uuid}%} to "red"
        command "/team join blue @a[team=temp]"

            if {team.%loop-player's uuid%} is not set:
                set {team.%loop-player's uuid%} to "blue"
        broadcast "&eチーム分けが完了しました"
